Arria 10 DMA PAC card

[khyam]

Hi,

The dma_afu_unsigned.gbs configured on PR region Arria 10 1.2.1 PAC fpga.  I am unable to run dma SW example on HW.  It gives me the following error: 

Running test in HW mode

ErrorfpgaDmaOpen: no memory

ErrorfpgaDmaClose: invalid parameter  

To solve the above error run the following command

sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\2048kB/nr_hugepages"

sudo LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH ./fpga_dma_test 0

sudo LD_LIBRARY_PATH=.:/usr/local/lib perf stat -d -d -d -D 20 ./fpga_dma_test 0 -m -c -n -y -C -M

I am unable to run the above command due to the superuser permission required in devcloud. I don't have superuser permission. 

Can you help me resolve the issue to run the command at the user mode?

Thank you.

Can you try run:

sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\2048kB/nr_hugepages"

LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH ./fpga_dma_test 0

LD_LIBRARY_PATH=.:/usr/local/lib perf stat -d -d -d -D 20 ./fpga_dma_test 0 -m -c -n -y -C -M

To run above commands are required sudo permission, without sudo, It won't work, throw an error.
